Dilution Volume Calculator
Audit actual surveyed excess extraction cross-sections against independently assigned ore envelope, not assay dilution or inverse planar skin mass fraction. Caller independently verifies units, applicability and matching conditions; no operational recipe, safety certification, causal efficacy or legal/resource classification is inferred.
Description
Excess extraction volume compares an as-mined cross-section with an independently established ore envelope.
Excess extraction volume compares an as-mined cross-section with an independently established ore envelope.1
The difference must share a matched extraction interval.
When to use Dilution Volume Calculator
Use this tool to calculate or review the supplied observations under the stated rules. Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.
How to use Dilution Volume Calculator and understand its results
- Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.
- Enter observedAsMinedCrossSectionsM2, callerIndependentOreCrossSectionsM2, observedMatchedExtractionLengthsM, using the field meanings and rules below, then run the tool.
- Read observedExcessExtractionDilutionM3. Inspect nested result fields where present, and review unknown records separately from known matches.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedAsMinedCrossSectionsM2 | Observed as mined cross sections m2 | list of number | Required |
| callerIndependentOreCrossSectionsM2 | Caller independent ore cross sections m2 | list of number | Required |
| observedMatchedExtractionLengthsM | Observed matched extraction lengths m | list of number | Required |
Use aligned nonnegative mined and ore areas and positive extraction lengths. Require minedArea≥oreArea per row, multiply the difference by length and sum.
dilutionVolume=Σ(minedArea_i−oreArea_i)length_i Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| observedExcessExtractionDilutionM3 | Observed excess extraction dilution m3 | number |

}Limitations and assumptions
Units, ledger boundaries, survey interpretation and model applicability must be independently established. These summaries do not assign reserve/resource classifications or establish support adequacy, ventilation safety or an operating setting.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries; ordinary string lists allow at most 128 strings of 128 UTF-16 units each; numeric matrices allow at most 128 rows and 128 columns, subject to narrower requirements above.
Alternative or Complementary methods
For a related step, use Mining Dilution Percentage Calculator: Mining dilution on a dry-mass basis separates recovered ore and diluent after moisture corrections. For a complementary comparison, use Ore Loss Skin Thickness Calculator: An equivalent ore-loss skin thickness divides surveyed unrecovered volume by independently exposed ore-face area.
